Capabilities / Channel Letters

Channel letters: front-lit, halo-lit, and combo-lit.

Front-lit, reverse-channel halo-lit, and face-and-halo combo letters with LED modules, low-voltage transformers, raceway or flush mount. Aluminum returns, acrylic faces, trim cap. Fabricated to drawing and installed to tolerance.

Overview

The exterior brand letter that reads day and night.

Channel letters are individually fabricated metal-and-acrylic letter forms lit from the inside with LEDs. They're the standard exterior brand letter on retail, hospitality, and corporate facades. Our network handles fabrication, electrical, mounting, and commissioning in every U.S. market, and we hold one documented spec so the letters look the same whether they go up in Dallas or Denver.

Lighting types

Front-lit, halo, or combo. The light changes the read.

01Front-lit

Front-lit

Fig. 03.A.02.01
FACEALUMINUM RETURNWALL
LED modules sit behind a translucent acrylic face and push light straight out the front. This is the brightest, most legible read by day or night, and the default for retail and high-traffic storefronts where the letter has to carry all the way across a parking lot.
02Halo-lit

Reverse halo-lit

Fig. 03.A.02.02
FACEALUMINUM RETURNWALLSTANDOFF
An opaque metal face on a standoff, with LEDs facing the wall so light spills around the letter as a soft halo. This is the premium, corporate look. The letter stays crisp in daylight and glows at night without a lit face.
03Combo

Face-and-halo combo

Fig. 03.A.02.03
FACEALUMINUM RETURNWALLSTANDOFF
A translucent face on a standoff lights both directions at once: a lit face plus a halo behind it. It's the richest look, and the hardest to balance, since it takes the most LED and power. We spec module count and standoff depth to the geometry of each letter.
Materials we typically specify

Aluminum, acrylic, trim cap, LED modules.

Returns
0.063″

0.063-inch or 0.080-inch aluminum, painted to a PMS-matched finish or brushed-aluminum natural.

Faces
3/16″

Cast acrylic with translucent vinyl overlays, or routed pan faces for push-through detail. White, color-matched, or day-night opaque vinyl for halo-only.

LED modules
5–7 yr

Brand-name modules (Principal LED, SloanLED, US-LED) with manufacturer warranty, on UL-listed low-voltage supplies.

Trim cap
1″

1-inch standard, painted to match face or return depending on the design read.

Power supplies
+20%

UL-listed and IP-rated for exterior use, sized 20% over peak load so the unit never runs flat out.

Fabrication notes

Where channel letters succeed or fail.

Good materials don't save a bad build. Two things go wrong most often. The first is LED module layout. Too few modules and the letter has hot spots and dim corners. Too many and the heat shortens the modules' life, so we spec module count per square inch of face area rather than by letter height. The second is the trim cap radius. A tight radius on a small letter cracks under thermal cycling, so on letters under 10 inches we use a thicker trim cap or a slight bevel on the inner radius.

Installation considerations

Raceway, backer, or flush — choose at survey.

  • Raceway mount. The simplest electrical, with one wall penetration, and the option most landlords prefer. Paint the raceway to disappear into the facade, or finish it to read as part of the design.
  • Backer panel mount. The whole letter set reads as one unit. Handy when letter spacing and a block of backer color need to reinforce the brand mark.
  • Flush mount.The cleanest read of the three. It needs a wall penetration per letter, and it's usually far easier on new construction than on a retrofit.
  • Electrical permit + inspection. Many jurisdictions require a separate municipal electrical sign-off. We route that through permits & compliance as part of the install scope.
Cross-links

What channel letters typically pair with.

A channel letter set is rarely the only sign on a storefront. It usually runs alongside window graphics for campaigns and seasonal messaging, dimensional letters for the secondary lobby read, and ADA wayfinding inside the door. Fabrication and permitting run through permits & compliance, and oversize letter sets bring in custom fabrication.
